Thumbnail Filmstrip of Grade TSS Glass Fiber Filter, Prewashed & Preweighed, 90mm, 1.5µm, EPA Method 2540, 100/Pk Images
Featuring prewashed and preweighed glass microfiber technology delivering validated Total Suspended Solids analysis for water and wastewater monitoring applications. Method 2540 D of Standard Methods for the Examination of Water and Wastewater1 compliant construction with 1.5µm retention efficiently captures suspended particulates while maintaining rapid filtration rates. Individual serial number identification with barcode scanning capability streamlines laboratory workflows and ensures complete sample traceability for regulatory compliance protocols.
Key Glass Microfiber Membrane Characteristics
- Binderless glass fiber construction eliminates organic contamination and delivers consistent gravimetric results
- 1.5µm pore size captures suspended solids with exceptional retention efficiency for reliable TSS determinations
- Prewashed with reagent grade water removes manufacturing residues and achieves constant tare weight accuracy
- Hydrophobic surface chemistry resists sample adhesion while facilitating complete liquid passage during vacuum filtration
- High loading capacity accommodates large sample volumes without premature clogging or flow rate reduction
Key Construction Characteristics
- Individual aluminum weighing pans provide contamination-free storage and direct oven transfer capability
- Preweighed to 4 decimal place resolution eliminates tare preparation time and reduces analytical variability
- 90mm diameter accommodates standard filtration apparatus and high-volume water sample processing
- Human-readable serial numbers with barcode identification enable complete chain of custody documentation
- Desiccated and oven-dried preparation ensures moisture-free baseline weights for accurate mass determinations
LE-TSS-WDT-9000 filters deliver validated 0.5 mg/L detection limit for 1-L samples optimized for environmental monitoring, maximizing your analytical precision while accelerating sample throughput in high-volume laboratory operations. Ready-to-use preparation eliminates time-consuming filter conditioning protocols, reducing your analysis time from sample receipt to final TSS calculation. Standard Methods and U.S. Environmental Protection Agency (USEPA) protocols1,2 compliance transforms these filters into reference-grade media, providing regulatory validation for your critical water quality assessments and discharge permit monitoring applications demanding both accuracy and analytical efficiency.
